stalks afterwards elongating and enlarging considerably; in V. 
odorata the leaves arise some little time before the flowers, 
which are about the same height or shorter, so as frequently to 
be hidden by the leaves. 
I have appended in a tabular form the characteristics of the 
two plants as I see them. 
Viola lirta. 
Tnodorous. 
Leaves shorter than the flowers 
at the time of flowering, generally 
one-half longer than broad. 
Hairs of the petioles and pedun- 
cles spreading. 
Sepals ciliate, hairy on the sur- 
face. 
Viola odorata. 
Odorous. 
Leaves as long as the flowers at 
the time of flowering, generally as 
broad as long. 
Hairs of the petioles and pedun- 
cles deflexed or adpressed. 
Sepals membranaceous at the 
edge, glabrous on the surface.

Series 3. (Accipitrina, Fries.)—Mode of propagation by closed 
buds. Stems leafy. Achzenia moderate in size. Rays of the 
pappus arranged in two obscure rows. 
H. strictum, Fries, has been reported from the neighbourhood 
of Bolton, in Wensleydale, apparently by mistake for Grizedale, 
in Westmoreland. H. prenanthoides, Vill., grows in the woods 
at Hackfall, on the south side of the Yore, which, during that 
part of its course, divides the North from the West Riding. 
9. H. tridentatum, Fries, Nov. 1819, p. 187.—H. rigidum, 
Hartm. in part.—Stem one to three feet high, leafy, rigid or 
flexuose, slightly hairy, paniculato-corymbose above. Leaves 
more or less numerous, with a few teeth on each side about the 
middle; lower ovate-lanceolate, slightly stalked; upper smaller 
and narrower, passing gradually upwards into bracts. Involu- 
eres ovate at the base when the plant is in flower, ventricose and 
constricted at the middle afterwards, like the erecto-patent pe- 
duncles clothed with white stellate down and a few black hairs 
and sometimes sete. Heads of flowers rather smaller and more
